PURPOSE To evaluate their susceptibility to audiogenic seizures, five groups of knockout mice with various forms of fragile X genetic involvement [hemizygous males (n = 46), and homozygous (n = 38) and heterozygous females (n = 45), and their normal male (n = 45) and female (n = 52) littermates] were studied. METHODS All mouse groups were tested at ages(More)
It has been proposed that interval 6 of the human Y chromosome contains the gene or genes that control spermatogenesis (AZF, azoospermia factor). We have studied this region in 33 patients with oligo- or azoospermia, using PCR amplification of the YRRM1 (RBM1) gene and of 13 sequence-tagged sites (STSs), all mapping within interval 6. Six of the 33 patients(More)
Using array comparative genome hybridisation (CGH) 41 de novo reciprocal translocations and 18 de novo complex chromosome rearrangements (CCRs) were screened. All cases had been interpreted as "balanced" by conventional cytogenetics. In all, 27 cases of reciprocal translocations were detected in patients with an abnormal phenotype, and after array CGH(More)
The long arm of the Y chromosome contains genes mapped in loci involved in male infertility, short stature and gonadoblastoma. However, many of these genes have not been fully characterized, and are not currently investigated in patients affected by such diseases. We report a study aimed to the genomic characterization of 5 genes mapped within the Y(More)
The 677T allele of the MTHFR gene has been suggested to represent a factor of risk for male infertility. In order to confirm this association, we investigated the presence of the 677T allele in 93 Italian infertile patients, selected after the exclusion of other possible genetic causes of infertility, and in 105 Italian fertile controls. The homozygous(More)
OBJECTIVE To evaluate the accuracy of a new subcutaneous glucose sensor (Glucoday; A. Menarini Diagnostics) compared with venous blood glucose measurement in type 1 and type 2 diabetic patients. RESEARCH DESIGN A multicenter study was performed in 70 diabetic patients. A microdialysis fiber was inserted subcutaneously into the periumbelical region and(More)
Cytogenetic investigations and molecular analysis of the Y chromosome by the polymerase chain reaction amplification of sequence-tagged sites (STS-PCR) technique were performed in 126 patients affected by idiopathic oligo-azoospermia following accurate selection of cases. Seventeen patients evidenced an abnormal karyotype. Fourteen patients with a normal(More)
Gout is primarily a disease of middle-aged males and is unusual in females and adolescent males. We describe 21 young men and women (mean age 28 years) referred because of precocious onset of gout or hyperuricaemia. Fifteen patients had a family history, but known hereditary causes of primary or secondary hyperuricaemia were excluded. A high proportion(More)
